public int intValue()

public boolean equals(Object obj)
true
if and only if the argument is
not null
and is a Float
object that represents a float
that has the
identical bit pattern to the bit pattern of the float
represented by this object. For this
purpose, two float values are considered to be the same if and only if the method
Float.floatToIntBits(float)
returns the same int value when applied to each.
Note that in most cases, for two instances of class Float
,f1
and f2
,
the value of f1.equals(f2)
is true
if and only if
f1.floatValue() == f2.floatValue()
also has the value true
. However, there are two exceptions:
f1
and f2
both represent Float.NaN
, then the
equals
method returns true
, even though Float.NaN==Float.NaN
has
the value false
.
f1
represents +0.0f
while f2
represents -0.0f
,
or vice versa, the equal
test has the value false
, even though
0.0f==-0.0f
has the value true
.
